Packet Filter Types
For any box selected, the Protocol and Port Filtering feature blocks the associated protocol type.
Examples are provided in Protocol and Port Filtering with NAT Disabled on Page 436.
To filter packets in any of the user-defined ports, you must do all of the following:
• Check the box for User Defined Port n (See Below) in the Packet Filter Types section of this
tab.
• In the User Defined Port Filtering Configuration section of this tab, both
o provide a port number at Port #n.
o check TCP, UDP, or both.
If the DHCP state parameter is set to Enabled in the Configuration => IP tab of the AP, do not
check the Bootp Client option for Packet Filter Types in its Protocol Filtering tab, because doing
so would block the DHCP request. (Filters apply to all packets that leave the AP via its RF
interface, including those that the AP itself generates.) If you want to keep DHCP enabled and
avoid the blocking scenario, select the Bootp Server option instead. This will result in responses
being appropriately filtered and discarded.
Filter Direction
Select which direction of traffic should be filtered – Upstream (uplink) or Downstream
(downlink).
User Defined Port Filtering Configuration
You can specify ports for which to block access. For more information, see Filtering Protocols and
Ports on Page 435.
Unit Settings Tab of the AP
An example of the Unit Settings tab of the AP is shown in Figure 85.
